  • Implemented and productionalized 12 health insurance client member data warehouses in our PostgreSQL and SQL Server environments, which involved creating a unique data integration template with SQL script, loading and quality assessing the member information, benefit plans, and member accumulations, and publishing the data to the production environment
  • Designed and developed 3 programs that provided new opportunities to our team, including a Python script EDI 834 ETL processor to allow for clients to send us files in EDI format, a Jenkins automation job in Shell Script that transferred our files from our AWS S3 data lake SFTP to our Jenkins box for processing, and a Jenkins automation job in Groovy that filtered the client’s latest uploaded SFTP file
  • Adjusted and enhanced 9 programs within our team’s system, including improving our generic client data integration template in SQL script, adding a reset check with Python to our Jenkins output when it would detect duplicate member records during the ETL process, remodeling various Jenkins jobs’ Groovy scripts to run more efficiently, and other internal improvements
  • Remodeled a client’s SQL script data integration template and Jenkins Groovy automation flow in 33 different instances by either repairing the template and flow following a file modification or a system failure or modernizing older templates and flows to match our current standards
  • Executed and quality checked 54 urgent and unplanned ETL file loads to the client data PostgreSQL or SQL Server warehouses, for reasons such as clients sending in new test files, clients missing their automation schedule, etc.
  • Generated 10 SFTP user profiles in our AWS S3 data lake environment using ssh public keys, and established myself as go-to for Data Governance due to my efficiency
  • Conducted 38 GitHub pull request QA reviews to provide my teammates feedback on their implementations/updates, point out any missing elements in the code, and merge the branch
